To provide photographers with a broader perspective about mobiles, lenses and cameras, here are links to articles, reviews, and analyses of photographic equipment produced by DxOMark, renown websites, magazines or blogs.

We’ve analyzed the image quality of 33 lens models, around 70% of the current range using the native MFT mount, on the new Olympus OM-D EM-10. Read on to find out which of those lenses perform best and which, if any, you should try and avoid when paired with the new camera.

Following the lens recommendations for Lumix DMC-GX7 we’ve now analyzed the image quality of Panasonic’s diminutive GM1 with over 33 lenses to assess the imaging characteristics specifically with the new camera. Read on to find out which of those models you should be using, and which, if any, you should try and avoid.

We’ve had the opportunity to analyze the image quality of Panasonic’s high-end 16-Mpix Lumix DMC-GX7 mirrorless camera with over 70% of the native mount lenses that are currently available (for it). We’ve scrutinized a total of 33 Panasonic, Olympus and Sigma made lenses to assess the imaging characteristics specifically with the new camera. Read on to find out which of those models you should be using, and which, if any, you should try and avoid.

The Olympus OM-D E-M1 is the new flagship model in the range and features a newly-designed pro-grade body and a modified 16-Mpix sensor incorporating on-chip phase-detection pixels for backwards compatibility with the firm’s 4:3 lenses.

While we’ve not analyze the performance of those earlier lenses on the E-M1, we have assessed the image quality of 33 models (more than 70% of the current range) using the native MFT mount.

Read onto find out which of those lenses perform best when paired with the camera.

Introduced alongside the firm’s new top-of-the-range OM-D E-M1 model, this new pro-grade standard zoom is the long awaited rival to Panasonic’s constant aperture G X Vario 12-35mm f2.8 ASPH model. Read on to find out how well it performs.

The depth of high quality primes and zooms for the PEN is, arguably, the most compelling reason to invest in the Micro Four Thirds system over rival mirrorless camera offerings. If you’re already a PEN E-P5 owner or you’re looking for advice or insights in lens performance in advance, this guide will aid you in making the right choice. Read onto find out which lens models in the range perform best optically.

As with previous guides, this review is intended to help you make the right choice when selecting lenses, in this instance, for the micro Four Thirds Olympus OMD E-M5 and the rival offering from Panasonic, the Lumix DMC-GH3. These two flagship models share not only the same mount, as partners of the Micro Four Thirds alliance, but in this particular instance, a similar 16Mpix MOS sensor as well. The prevalence of high quality primes (and let’s not forget zooms) for those cameras makes it, arguably, the most attractive proposition of any of the mirrorless camera systems currently available. Read on to see which lens models are the best performing in the range.

When zoom lenses were first beginning to be viable alternatives to a bagful of prime lenses back in the 1980’s there were two focal length ranges that were dominant, 35-70 and 70-200: the ‘standard zoom’ and the ‘tele zoom’. Well this ‘old’ approach seems to be back, Panasonic’s 35-100 for their Lumix range exactly matches the 70-200 range while their 12-35 that we reviewed recently fills the ‘standard’ slot.

The Micro 4:3 market is full of technology, each new generation apparently having some new enhancement, with a new, more superlative name. Panasonic is no different, but this new Lumix G VARIO 14-42 f3.5-5.6 II Asph. Mega OIS carries neither the ‘Power Zoom’, or the ‘Power O.I.S’; there are aspheric elements but no ED glass. Without all the latest refinements is it worth having at all? Yes, it is: well priced and punches above its weight.

The Micro 4:3 market is maturing nicely: there are products available now to suit a wide range of needs. Up to now the upper end of this sector consisted entirely of fixed focal length lenses, but the Panasonic LUMIX G X Vario 12-35mm f2.8 ASPH. Power O.I.S changes all that. This is the first ‘standard’ zoom lens that DxO Mark has tested that really competes with fixed lenses on this format.

It's almost four years since Panasonic introduced the first mirrorless interchangeable lens camera in the shape of the Lumix DMC-G1, a most unrevolutionary-looking product that ushered in a brave new era of camera system design. In the intervening years we've seen a slew of cameras of this type as all of the major manufacturers (with the curious exception of Canon) have joined the fray. We've also seen a welcome resurgence of compact fast primes along with the development of clever collapsing zooms, as manufacturers have sought to capitalise on the inherent size advantage over SLR designs. But one type of lens highly valued by more-serious photographers has been conspicuous by its absence - the high quality, large aperture zoom. Panasonic has now addressed this with a lens it's labelling H-HS12035 - an optically-stabilized 12-35mm F2.8 in its premium 'X' range.

Pansonic vs Olympus

How is it you have awarded the Olympus 12-40 f2.8 an overall score of 20 (Olympus OM-D E-M1 body) but only 19 for the Panasonic 12-35 f2.8?

They both score the same for sharpness - 9The Panasonic has better transmission (T-stop) - 3.1 (Pana) vs 3.3 (Oly)less vignetting - -0.8 (Pana) vs -0.9 (Oly)less distortion - 0.9% (Pana) vs 1.3% (Oly)Only on the Chromatic aberration test does the Olympus score better than the Panasonic and then by only 1um.They are both pretty close in performance, but it seems to me the overall scores should be reversed.

good comparison

this is good to see the comparison with the Oly 12 and Oly 45, from the graphs it looks like we just need to go for our personal preference: 12 & 45 on a PEN vs the 12-35 on the OMD ... these give very different size solutions and of course that extra stop for the primes

Better than the Canikon?

Interesting comparison. Why not compare to similar lenses in other format like what was done with the 35-100/2.8?

Anyway, this lens is a good one. It has better overall score than both Canon and Nikon 17-55/2.8 with better sharpness and CA than the Canon and better transmission and vignetting than both:http://www.dxomark.com/index.php/Lenses/Compare-Camera-Lenses/Compare-lenses/(lens1)/173/(brand)/Nikkor/(camera1)/0/(lens2)/960/(brand2)/Panasonic/(camera2)/0/(lens3)/169/(brand3)/Canon/(camera3)/0

Re: Better than the Canikon?

First, get a clue about which lens to compare with. Pana 35-100 needs to be compared with 70-200/2.8 from Canon and Nikon on a FF sensor. The dinky m43 lens isn't in the same universe as the Canon and Nikon equivalent.

Re: Better than the Canikon?

My bad. I saw the comments from the 'Forums' page. It didn't have a link back to the lens page you were commenting about. I just saw 35-100 and assumed you were talking about that lens. Now, I know you're talking about the 12-35 lens. The forums page is very poorly done on this site.
